The Milltek Sport Large-Bore Downpipe with Catalyst Delete for the Mini Cooper S R56 R57 R58 R59 is engineered for drivers seeking maximum performance gains and enhanced exhaust flow.
Fabricated with a larger diameter than OEM parts, these downpipes allow significantly more exhaust gas to exit the engine, improving efficiency and unlocking additional power. When used with the included Catalyst Bypass Pipe, the system delivers significant gains without the restrictions of a traditional catalytic converter.
This product is intended for track use only and must be paired with a Stage 2 ECU remap to safely achieve performance improvements.
